Inventor: TAKAHASHI TOORU
IPC: B41J2/30
Filed: 1990-12-26
Abstract: PURPOSE:To enable specific voltage to be applied to a motor even though supply voltage is fluctuated according to printing information. CONSTITUTION:When a conduction ratio is calculated by integrating a reciprocal of a supply voltage with a terminal voltage to be applied between terminals of a motor 16, a motor current is obtained from both a motor current target value and the conduction ratio. A consumed current value according to a position of a printing head is added to this motor current, and supply voltage drop is obtained from the added value. The supply voltage is calculated by estimation from both the supply voltage drop and deviation of the supply voltage under no-load. The conduction ratio is corrected according to this calculated value. Though the supply voltage is fluctuated according to printing information, a specific voltage can be applied to the motor, and printing quality can be prevented from deterioration due to fluctuation of the supply voltage.
